To all whom it may concern:

" Be it known thatI,"F' 1 1n -GODDARD, a citizen ofthe Unitedsstates,residing in the Icity,-county, and State of New York, have "lowing is aspecification. i

f My invention relates to improvements in invented new and usefulImprovements in Salad-Dressing Mixers," of which' the folmixingapparatus for 1thoroughlyf blending the various ingrejdients'of salad.dressing, and has for, its objects the provision of a simple, economicalandi eifeotive means-for beating in a saucer or bowl.

mixed liquids will normally [tend to flow French dressing, consistingfor example of approximately four. parts oliveoil and one part vinegarwith-the addition thereof of suitable flavoring; ingredients, it i ;is jextremely difficult to thoroughly commingle the said ingredients owingflto their. totally different properties and consistency. Mere beatingalone is not sufficient, as is'also the mere stirring, owing to'the factthat in the ,first case the oil-is broken up into numerous smallglobules which are distributed throughout the mixture and are noticeablyvisible therein, and inlthe secondvplace, the

mixture is streaked with ribbonsof the difbeing any thoroughblendingofthe same;

My inventionjisfully set forth and described in the following-detaileddescription and drawings'forming a part .of- 1 this specification, inwhicho a Figure 1 is a vertical entral section showing my improvedmixing device; andFig. 2 is a plan view,,from above-of the=same.

Referring to the drawings and the construction shown therein, thereference numeral 1 designates a receptacle or bowl, preferably ofglass, although any other suitable material, such as metal. or the like,may

be employed. The said bowl as shown, is

provided with curvilinear inner walls of gradually increasingcurvatureftoward the bottom of the receptacle in order that the i towardand collect in the .bottom of said bowl due to the action of gravitythereon. The said bowl is closed by a snug fitting top' 2,which isprovided with acentral ourii 2113, adapted to receive aish'aft 4, thelatoak, N x; ssmme m 'annns'r CU -Inn tan 1 consrrru'rnvs nn ria vr orGUR-RIERE:

ter beingconnected externally of said bowl witha handle 5,having a knobor hand-grip 6 on the free end thereof. Upon the opposite end of saidshafty'and below a ring or bear-h1g formedthereon to prevent verticalmovement of said shaft,is mounted a paddlewh'eelflorrotor consisting ofthree parabolicallyfcurvedblades 8 alliof corresponding size and shape,disposed at equal intervals around said shaft and rigidly securedthereto. shown isof sufficient extent to substantially contact with theside wall of said bowl at its point of'juncture with the bottom thereofas designated by the reference letter 'a.

Each of said" blades as Abovethis point said blades are of slightly lessradial extentbeing cut away to' afford an opening9 sufficient to admitOf'thepas sage "therethrough of mixed liquids." The top 10 of the saidblades projects radially so asto be substantially coextensive with the"lower end thereof. Asshown, each blade is provided with a series ofthree slightly inclined substantially parallel slots 11, all, 11", whichextend-throughout the greater portion of the breadth of said blades;These slots permit of the passage therethrough of the liquids containedin said bowl intermediate the outer edges of said blades. Preferablysaid slots extend at an angle of approximately 45 to the horizontal andare from 1; to 9;; inches in width and inch in length for a blade 1;;

inches at the outer edge and 2 incheshigh from the bottom to the. pointof contact with the ring 7 The bottom of each of said blades isapproximately rectilinear in order that the same can conform to, andsubstantially contact with, the bottom of said bowl or vessel at a pointalong said blades.

The operation of the said device is evident from the foregoingdescription, the same being as follows: The salad dressing, for examplea mixture consisting of say four parts of olive 0'11 and one part ofWine awheel is then applied. The operator then rapidly 'rotates the saidpaddle wheel, preferably about 120 revolutions per minute.

is introduced into the bowl, the paddle inserted thereinand the cover p,

105 a d i result the liquids will be forcibly thrown V permit of foldingtogether and periodically liftedf bodilyfrom the bottom of thereceptacle and thrown outwardlyagainst the Wall of the ves'sel or owingto the concave config- 5 uration of the sidewalls of said vessel and ifcentrifugal force, the liquid will be obviously thrown against the bowltoapprozp iinately the point' a. Any quantity of iqui m eov n mediae'the edges of the said blades is constantly forced through the seriesof slots in each ofsaid blades l it p c heme aid b ades being therebynot only is there constant comthe-portion in the center of the bowlislike- Wise repeatedly stirred and coniniingled.

.As shown in the dotted lines in Fig. 2, the blades of th paddle Wheelmay be jointed With respect to the shaft so as to the same, and therebyrender it possible to insert the mixing. de-. vice when folded throughthe relatively smalltop aperture of a large container. In

I such cases it is preferable that the blades be so connected to theshaft that they can open i into the position shoWn'in Fig. 1 when theoperating handle is rotated in a clock-Wise I direction,'and will beprevented from open- J ing farther, orfrom collapsing ba'ckwardly.

When it is desired to remove the mixing device, a few twirls of theoperating handle in an antirclock-Wise direction will col.- lapse theblades forwardly and permit of their removal from a mouth of .only halfthe size of the expanse covered bysaid blades when opened. ,i
